CAR DOOR.

Application filed April 8, 1924. Serial No. 705,093.

To all whom it may concern Be it known that I, Ivna P. BENDIKSON, acitizen of the United States, residing at Mandan, in the county ofMorton and State of North Dakota, have invented certain new and usefulImprovements in a Car Door, of which the following is a specification.

This invention relates to improvementsin car doors particularly designedfor freight cars.

An important object' of the invention is to provide a new and improvedcar door which may be slidably mounted upon a freight car and securelyheld in position thereon.

A further object of the invention is to provide a door of this characterwhich will not become opened or loosened caused by j arring of the carwhile traveling over the rails.

A still further object of the invention is to provide a door of thischaracter which may be opened or closed with little difficulty and atthe same time insure a tight connection.

A still further object of the invention is to provide a door of thischaracter which is comparatively simple 1n construction, although verydurable and efficient for this purpose. I

Other objects and advantages of this invention will be apparent duringthe course of the following description.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame:

Figure 1 illustrates the door embodying my invention mounted on the sideof a freight car,

Figure 2 is a similar view showing the door in partially openedposition,

Figure 3 is a top plan view of my 1mproved door,

Figure 1 is a horizontal section taken on the line 4:4: of Figure 1, I

Figure 5 is an end elevation of my inven tion, and

Figure 6 is a vertical sectional view taken on the line 6-6 of Figure 1.

In the drawings, wherein for the purpose of illustration is shown thepreferred embodiment of my invention, the numeral 10 generally denotesthe side of a freight car which may be used for transporting cattle,

grain or any merchandise usually transported. in en in ers. Myjrnproveddoor structure generally denoted the numeral 11 eensista er a pluralityof longii'yiidinal fgitaiiks 12 securely fastened by means of aplurality of upright connecting planks .13. I do not wish to limit myinvention to this construction however as the door may conceivably beconstructed as a solid sliding partition, the construction dependingupon the form of merchandise to be carried in the freight car. The typeherein illustrated being particu larly adapted for stock care, while Ido not wish to limit my invention to this particular application andconceive of applying the door to grain cars and the like. The type ofdoor shown in the accompanying drawings is adapted to slide within asuitable frame built in the side of a freight car and embodies novelsecuring features.

Mounted in the central portion of the door I provide a sliding bar 14which is preferably circular in cross section and is actuated by asubstantially U-shaped handle lever 15 which extends outwardly beyondthe upright members 13 and has its extremities secured to the bar 1 1. Apair of longitudinally extending bars 16 are secured to the threeuprights positioned in the frontportion of the bar and are preferablyconstructed of metal forthe purpose of reinforcing the structure of thedoor. The front pair of uprights 13' each carry a pair of raised guidebars 17 adapted to permit movement of a pair of swinging arms 18. Theswinging arms 18- are pivotally connected to the center upright near theupper and lower extremities thereof, and have an enlarged engaging head19 formed on the front extremity provided with a rectangular opening inthe center.

The swinging arms 18 each carry a pair of tapered bars 20 pivotallyconnected to the arms as at 21 and adapted to swing therewith. As it isintended to retain the tapered bars 20 in a substantially verticalposition I provide a pair of blocks 22 and 23 secured against theuprights 13 to prevent displacement of the said tapered bars: Theforward upright of the door carries a pair of arcuate levers 24positioned near the upper and lower extremities and hingedly secured tothe upright by means of straps 25 and pins 26. The inner extremities ofthe levers 24L carry a pair of swinging bolts 27 hingedly connected tothe levers. The outer extremities of thearcuate levers 24 are turnedoutwardlyas at 28 to form actuating, clips to ermit, the levers to bereadily swung about t eir' "lvtit pins.

(rte bane 2? adapted as engage sate 2 reraeoo able sleeves 29 formed onthe outer portion of brackets 30 secured to the door frame. In order toprevent n'iovement oi the levers when in the closed position I provide apair of swinging cam members 31 pivoted adjacent the levers and adaptedto be positioned in the retaining straps 25 and prevent displacement ofthe levers whereby the bolts 27 are held in the sleeves 29 as shown inFigure 1.

The upper portion of the door frame has a. metallic strip securedthereon, the outer extremity being turned to provide hinged joints. Aswinging plate 33 has coacting turned edges adapted to align with thesaid hinged joint and adapted to receive a circular hinge rod 34:forming an axis about which the plate 33 may be rotated. The turnededges of the co-acting plate are constructed to permit a space to beformed between the supporting strip and hinged plate thus enabling theplate 33 to be moved longitudinally as well as swung easily about therod. The swinging plate 38 is provided with rectangular openings 2-56adapted to receive the extremities of the tapered bars 20 one edge ofthe opening being provided with a tapered slot for the purpose ofreceiving the shank of a pair of retaining bolts 37 secured to the doorand provided with enlarged heads 38. A retaining knob is also secured tothe metallic strip as denoted by the numeral 39 and is adapted to engagea swinging latch 40 pivoted to the plate 32 for the purpose ofpreventing movement of the swinging plate in closed position. r

The lower extremity of the door frame carries a bracket 4-1 bolted orotherwise secured thereto, intermediate portions of the bracket beingbent outwardly as at 42 for the purpose of receiving the lower taperedbars 20 and assisting the door closure. In order to prevent movement ofthe U-shaped handle lever 15 I provide a hinged bracing plate 4:3hingedly mounted upon the central upright and provided with a recess 4%at its extremity, the said recess being adapted to engage the handlelever 15 in the closet po- 'sition. A pair of extending prongs areformed on the extremity of the bracing plate 4:3 and rest upon thelongitudinal bars 16 when the plate is in the closed position andengaging the lever 15. The end jamb of the door frame is provided with agroove in the central portion thereof covered by a cover plate 45secured in the central portion of the jamb and adapted to receive thecircular bar 14.

In operation, when the car is being transported the locking devices arein closed position and securely retain the door in position. lVhen it isdesired to open the door as shown in Figure 9 the bracing plate 13 1Sswung outwardly permitting the U-shaped lever 15 to be movedlongitudinally toward the rear of the door and releasing the bar 1 1from the door frame. The next operation consists in swinging the cammembers 31 away from the retaining straps 25 and swinging the arcuatelevers 2d causing the bolts 27 to be withdrawn lirom the sleeves 29. Thearms 18 which have their extremities positioned over the sleeves 29 arethen forced upwardly and released from the sleeves and. swung toward thecenter of the 'door carrying the tapered bars 20 there with andreleasing them from the bracket 41 and plate 33, the plate 33 beingforced longitudinally thus releasing same from the bolts 37 and freeingthe door.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as the preferred example of the same, and thatvarious changes as to the shape, size and arrangen'ient of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claims.
